Have to close and reopen app to switch songs – Christmas Song Collection Review

When you get to the end of song (and haven't made purchases), a pop up asks you to buy the songs. There is no way to get out of this, to go to another song, without closing the app and then reopening it. My 3 year old loves the songs but gets frustrated because of this. Deleting it.
